GENERAL DESCRIPTION
The PCF8881 is a low-power single chip TFT LCD driver
with integrated source driver, gate driver, display RAM,
timing control and DC-to-DC converter. The IC is a single
chip solution with a minimum number of external
components (capacitors).
The PCF8881 has 396 source and 132 gate outputs
(132
× RGB Sources × 132 Gates). The integrated display
RAM has a capacity of 279 kbits
(132 Sources
× 16 bits × 132 Gates). The PCF8881 can
drive a 132 RGB column
× 132 line LCD panel with
65 kbyte colours when using the internal RAM.
